Typical replacement is the calculator's reference roof: a 2,000 sq ft single-story home, 6:12 pitch, standard hip roof, architectural asphalt shingles, single-layer tear-off. Index 100 = US average. Get your local number with your ZIP for metro-level pricing and other materials.

Roof replacement cost by state: reading the table
Every state row above prices the same reference roof: 2,000 square feet, single story, 6:12 pitch, standard hip, architectural asphalt, single-layer tear-off. So the differences you see are purely location. The index column compares each state to the US average of 100, and the dollar column turns that into a real number against the $23,050 US-average job. The spread is worth caring about: Arkansas comes in lowest at $19,826 and Illinois highest at $26,886. Same roof, $7,060 apart.
Why the same roof costs $7,000 more in some states
Labor, mostly. Installation is the biggest slice of a roofing bill, so this index weights local roofer wages as its largest input, straight from Bureau of Labor Statistics data, with regional overhead and material costs behind it via BEA Regional Price Parities. That's why the map looks the way it does: the South and parts of the Midwest pair lower wages with lower living costs, while Illinois, New Jersey, the Northeast corridor, and the West Coast stack higher wages on higher overhead. Texas lands about 11 percent under the US average at $20,745. California runs about 13 percent over at $25,650. Building codes add real cost in specific places too, like hurricane-zone fastening and underlayment rules, and the estimator's optional local-conditions toggles cover those.
State averages vs your ZIP code
Metro differences inside a state can be as large as the state-to-state spread. Once you've got your bearings here, get your real number: the roof cost calculator prices your roof at metro level from your ZIP, using the same verified index this table is built on.
Frequently asked questions
What state has the cheapest roof replacement?
On this verified index, Arkansas, at $19,826 for the reference roof, with Mississippi basically tied at $19,847. Both sit about 15 percent under the US average.
Why is my quote different from my state's number?
Three usual reasons: your roof isn't the reference roof, your metro prices differently than your state average, and your material choice moves the number more than geography does. The calculator handles all three.
Do these differences apply to repairs too?
Yes. Repair bands scale on the same regional index, so a $1,150 typical moderate repair at the US average prices higher in Illinois and lower in Arkansas. The repair calculator applies it automatically.
